Based on characteristics testing of the filling material, the related calculation was performed on the filling slurry gravity transport by pipelines.
For the slurry prepared from different materials, due to the big difference of composition particle settlement and penetrating properties, obvious difference also exist in the flow mechanism of slurry [7-8].
Therefore, for new filling system in mines, analysis and research on the properties of the filling material and the flow mechanism of slurry are necessary.

Introduction
Multi-purpose smart materials are used in the realization of smart structures since they have self diagnostic and self controlling capacity.
Such problems are overcome by using the Functionally Graded Materials (FGM) which are microscopically inhomogeneous composite materials exhibiting smooth and continuous change of material properties along the thickness direction.
Stainless steel is high strength material but it can rust in extreme cases and aluminum doesn’t rust but it is low strength material.

Introduction
As clay materials has certain adhesion effect, so when clay materials move, there is the relative velocity between layer and layer, thus the clay materials squeezed out from the movement will be stratified [1].
After measurement [8], clay materials Newton viscosity ηN =1.09×103Pa•s, plastic viscosity ηP=1.09×103Pa•s, apparent viscosity ηS=2. 37×103Pa•s, the yield limit clay materials fv=1.018×104Pa, reamer speed for N = 30r/min.
(2) The thickness of clay materials pasted on the modified hub can be decreased by 50%.
The thickness of clay materials pasted on the modified Spiral face can be decreased by 42.3%.
